Agroforests can play an important role in biodiversity conservation in complex landscapes. A key factor distinguishing among agroforests is land-use history – whether agroforests are established inside forests or on historically forested but currently open lands. The disparity between land-use histories means the appropriate biodiversity baselines may differ, which should be accounted for when assessing the conservation value of agroforests. Specifically, comparisons between multiple baselines in forest and open land could enrich understanding of species’ responses by contextualizing them. We made such comparisons based on data from a recently published meta-analysis of the effects of cocoa (Theobroma cacao) agroforestry on bird diversity. We regrouped rustic, mixed shade cocoa, and low shade cocoa agroforests, based on land-use history, into forest-derived and open-land-derived agroforests and compared bird species diversity (species richness, abundance, and Shannon's index values) between forest and open land, which represented the 2 alternative baselines. Bird diversity was similar in forest-derived agroforests and forests (Hedges’ g* estimate [SE] = -0.3144 [0.3416], p = 0.36). Open-land-derived agroforests were significantly less diverse than forests (g* = 1.4312 [0.6308], p = 0.023) and comparable to open lands (g* = -0.1529 [0.5035], p = 0.76). Our results highlight how land-use history determined the conservation value of cocoa agroforests. Forest-derived cocoa agroforests were comparable to the available – usually already degraded – forest baselines, but entail future degradation risks. In contrast, open-land-derived cocoa agroforestry may offer restoration opportunities. Our results showed that comparisons among multiple baselines may inform relative contributions of agroforestry systems to bird conservation on a landscape scale. 相似文献

Activated carbon was prepared from coconut shell, an agricultural waste, for the removal of phosphorus from synthetic phosphorus‐containing wastewater. The activated carbon obtained from the coconut shell was characterized using Fourier‐transform infrared (FTIR) spectroscopy. Batch mode experiments were conducted to study the effects of pH, particle size, adsorbent dosage, and sorption time on the adsorptive potential of the prepared activated carbon. Response surface methodology was employed to study the interactions among the variables and to optimize the process conditions for the maximum removal of phosphorus using the coconut shell–based activated carbon (CNS). The characterization results from the FTIR showed the presence of variety of functional groups, such as ?OH, ?NH, C=O, C?H, C?N, CH3, and CH2, which explains the CNS's improved adsorption behavior on the colloidal particles. A maximum performance of 95.22% was obtained for CNS at the optimum conditions of adsorbent dosage = 1,000 milligrams (local variable), pH 2 (local variable), particle size = 0.2 millimeters (local variable), and sorption time = 4.2 hours (global variable). 相似文献

Scenario analysis is a technique that is increasingly being used as a way of identifying future policy options and issues in the long-term. This paper discusses the role of scenario analysis in policy development in relation to future transport policy. It discusses three key stages in scenario analysis: the identification of policy targets; the development of images of the future; and the construction of policy packages. 相似文献

The threat of wildfires to the economic potential of forestry and agriculture is one of the persistent national and international
concerns. Improving and applying indigenous wildfire management (IWM) approaches is seen as one of the main hopes for mitigating
and adapting to this threat to rural forest communities. Identifying the contextual causes and adaptation measures practiced
by local people is essential for planning an appropriate mechanism for IWM. Yet only limited studies are available on IWM
practices and most of those studies were conducted outside of this study region. To fill this gap, this study examined the
wildfire mitigation and adaptation methods of forest communities in Ghana using interviews with 266 farming households. Their
perceptions of the causes, cost and risk factors were also examined. The result suggests that wildfires are annual events.
More than half of the wildfires reported were caused by slash-and-burn land preparation, with hunting-related fires in second
place. Forest households loose about 208 Ghana cedi (US$ 231 in 2006) in value due to damaged crops and tree seedlings annually
(i.e. about 50% of annual income of a Ghanaian farmer). The respondents had the operational skill and coping abilities to
deal with small-scale wildfires and were supported by well-established local arrangements, community rules and silvicutural
techniques. In addition, they were well informed about the basic risk factors (e.g. fuel load, climate, and presence of ignition
triggers) and how these can interact to cause devastating wildfire. Therefore it is critical that policies and institutions
that promote IWM initiatives build on the strong underlying community knowledge and local networks to enhance their effectiveness. 相似文献

Industrial water conservation is an important adaptation to the effects of climate change. In addition to water conservation within individual plants, wastewater can be reused/recycled among different companies through inter-plant water integration (IPWI) schemes. Such schemes are based on the concept of industrial ecology and industrial symbiosis, and can be used to achieve greater water savings than when water conservation is implemented in individual companies separately. However, in IPWI, each participating company seeks to maximise its own benefits. In the absence of centralised authority dictating the terms of water integration schemes, conventional modelling techniques are not appropriate. This paper shows how a game theory-based approach can be used to analyse the interaction of participating companies in an eco-industrial park seeking to develop an IPWI scheme. 相似文献
